Resequencing of positional candidates identifies low frequency IL23R coding variants protecting against inflammatory bowel disease

Abstract

Michel Georges and colleagues perform high-throughput resequencing of 63 positional candidate genes identified through genome-wide association studies to search for rare coding variants influencing risk of Crohn's disease. They identify low-frequency coding variants in IL23R that confer protection against inflammatory bowel disease but conclude that rare coding variants in these positional candidates do not make a large contribution to Crohn's disease risk.
